New York City Mayor Michael Bloomberg will push to defeat Sen. Mark Pryor (D-AR) in 2014, according to a TIME cover story published Thursday.
Pryor voted against a bill that would have expanded background checks for gun purchases in April, and Bloomberg’s gun control group, Mayor’s Against Illegal Guns, ran ads in May calling for Pryor to change his stance on background checks.
Bloomberg did not specify what this push would look like, but it may involve discussing Pryor’s record with Democrats in Arkansas, according to the TIME story.
Bloomberg said that he backs any and all candidates who support gun control legislation.
“If you support reasonable background checks, I will support you, even though we have probably nothing in common on any other issue,” Bloomberg told TIME.
Bloomberg also spoke with TIME about the Colorado state senators that were recalled in September after voting in favor of a new gun control measure in the state. Bloomberg said that although the lawmakers were defeated, it was still a victory for gun control.
“What do you mean we lost? I’m sorry for those two people,” he told TIME. “But we won in Colorado. On to the next state.”
